International schools in Stockholm

Hi,

My husband has just got a job offer in Stockholm. We are a family of four (7,5 year old boy and 4,5 year old girl). I would greatly appreciate some advice regarding International schools for my children most specifically Stockholm International School and The British International School of Stockholm, i.e. are there long waiting lists? what is the level of education? any views regarding the teachers? what are the facilities? Which school is better?

Thanks in Advanced,
Anna
